In the thirty years since Biographies for Birdwatchers was published, the Western Palearctic bird Iist has lengthened. Vagrants and taxonomic revisions have added many new eponymic names to familiar ones such as Montagu's Harrier, Sabine's Gull and Steller's Eider. The expanded geographical range of this edition includes the Arabian Peninsula, Iran and parts of Central Asia, adding great ornithologists such as Christian Pander, Theodor Pleske and Nikolai Zarudny. Volume one contains 163 people who have full species named after them, volume two 179 people with subspecific eponyms.
